EDWARD J. SMITH, F CLEVELAND, OHIO, ASSIGNOR TO MARY E. SMITH, OFCLEVELAND, OHIO LAMP SHADE AND SUPPORT THEREFOR Application filed May 8,

My invention relates to lamp shades and supports therefor, andespecially concerns a lamp shade carrying a light bulb therein, and aclamping device for mounting the shade L upon an open music stand. It ismy especial purpose to provide a music stand supporting a horizontaltable or shelf together with a plate inclined somewhat to the vertical,but

having an upper curved edge upon which an illuminating member may bereadily detachably mounted.

It is understood that lighting attachments for music stands or desks areold in the art, but all of them, so far as I am aware, have the seriousobjection of either unduly shading parts of the support which should beilluminated, or are of such a nature, usually be cause of the design ofthe shade, that the light is too bright in many directions from itssource, and thereby produces an undesirable glare annoying to the user,and as I have found, quite unnecessary. It is an object of my inventionto concentrate the light from the shade employed upon the sheets thatmay be resting on the supporting plate, and confining the light raysthereon, as much as possible. I

It is a further object of my invention to provide a light shade ofgeneral triangular outline as shown in plan, having downwardly-extendingflanges upon the sides and peak of the triangle, but providing the baseof the triangular support with clamping flanges which are thus farremoved from the light F source.

Another object of my invention is the provision of a flanged shade oftriangular outline whose base is provided with means for mounting upon acurved plate, and whose I light bulb extends normally into the uppermostpeak of the triangle and opposite the supporting clamp.

It is a still further object of my invention to provide a shadetriangular in out line having downwardly-extending border flanges on allsides except the base line, which latter is provided with clamping meansfor engaging the convex surface of G a supporting rack plate, andproviding a 5 socket at the intersecting angle of the tri- 1929.

the supporting plate, and is narrowest at the point farthest from theplate. As the user of such a music stand is assumed to be positioned infront of the rack or supporting plate and facing the same, the desirableobject is attained of restricting the rays from the bulb most at thepoint nearest the user l Vith these and other objects of my inventionwhich will be made evident as the description proceeds, I have explainedthe structure of my lamp shade and support in the accompanyingspecification, recited the same in the appended claims, and illustratedthe same in the accompanying drawlngs', in

Figures 7 and 9 are sectional details as shown on the lines 7-? and 9-9of Fig. 4,

respectively, and

Figure 8 is a sectional detail as taken on the line 8-8 of Figs. 3 and4.

In the drawings I have illustrated the music stand supported upon avertical standard 10 having a horizontal plate or shelf 11 mounted onits upper end and a tubular holder 19 at one lateral edge of the shelf,but parallel with and integral with said stand ard. The connecting web 8d1rect.y supports the shelf 11. My improved supporting rack 12 has astraight lower edge to which is at tached the flange member 13, and anupward curved edge 1% in which a deep notch 15 is formed for a purposetobe explained later.

The rack is directly mounted upon an angu lar member 16 whlch ispreferably lntegra with the sleeve 17 secureo to an eloi rod 18 itselftubular and ilesigiet scopi ally in the holder 19, the the usual setscrew 20 for ing the rack. Lily shade 21 is tachably upon the said edge1;; and in a general plane substai angles thereto. The shell 11 w mainin a tired position upon t. the standard 1t will be supnereal c J.tionally. as by a tripon 22. Clo. an adjustment shoulder 9.

The curved edge 1 is convex, and my outline, an

curved edge fitting ove the rack 12. The edge M;

Short ears 526 are 1': l integral with one of the flung: andare provided with suitable apertures for receiving attaching; scr wsentering the u pper e l 14 of the rack. The point or the shade rartheshade,

The said pintle 32 is carrieiil l ly-extcnding ears from an a' dct:iably mount (l upon face 36 of the shade 21 about of, as shown in Figs.3. -il and or under surface of such plate with parallel and lOIT tUCllHQguided upon pa 'allel tracks in the shade.

The SUPPOltiIlg plate 35, together coral vith with the light bulb and iis mounting mechanism, is se-- cured adpistably on the inner surface of.the

light bulb 29 carried by the swinging plate 30 may be readily adjustedtoward and from the socket 28. Between the ears and the verto); 27 anotched partition 55 is provided inemral with the main wall of the shade21, as shown. in Figs. 3, 4t, and 6. This provides a positive positionfor the bulb resulting from mating the neck of the same in the notch 4A.

The tongue 2% is apertured at 45 to receive suitable insulated conductortherethrough, and may be its-elf insulated by a lining sleeve 46 asshown in Fig. In the northe 2). mal position of the light bulb 29, themount- 1g plate 30 assum a vertical position, when 1e standard 10 isvertical, a 1d the pressure 5 the spring 33 forces the plate upward andrwardly unt l itbcars against the standard in swinging ii ti 1' integralwith the plate upon its piutle therefore, the bulb 29 may movedownwardly and rearwardly, but cannot rise upwardly far enough to strikethe material of the shade.

As above described, my improved construction provid s a music rack 12adjustable vertically relative to the shelf 11 which is well adapted forreceiving various articles such as music SllQQLE-i and even parts ofinstruments, and boththe shelf and rack are illun'linated from the samesource without unnecessarily lighting space outsioe the generalboundaries The shade 21 is readily deof these areas. tach'ible from theconvex edge of the *acl; and the 1 ate carrying the bulb is adjustablelongitudinally within the shade. This together with the convenience ofswingthe bulb upon its hinge, forms a construction that willbeappreciated.

Reari'ardly from the light units will extend the usual conductor 48,passing through the sleeve 46 and thence downwardly through the parts1'? and 18, and therefrom to a suitable electrical connection.Considering the director or other user of the device as standing in aposition to face the rack 12, it will be seen that the flanged vertex 27wholly protects his eyes from the glare of the rays leavin o the bulb29, though the sheets-restingupon the rack 12 will be well illuminated.It is of especial'importance that the VCltGK 27 of the shade is iearestthe user, and that, due to the triangular outline of the shade, the areailluminated from this single bulb expands as the rack 12 is approached.The triangular form oi the shade Qltherefore, has the valuable qualityof illuminating a large field from a single bulb, at a point closelyadjacent the rack supporting the sheets to be illuminated, and ofintensifying the illuminating rays at points illum nated from the vertexof the c l iaoe.

Es )ecial advantages are claimed for this i u'iprovement in thatitadords a maximum of illumination from a single light bulb and therebyprovides better ight for musicians by minimum electric current. Thearra11gement of parts affords the greatest convenience in adjustment andin shifting to different parts of the room, as well as in lighting theshelf and rack from a single bulb.

Various changes may be made in the structure of the support an well asin the shade, and it is to be understood that some features may bemodified without departing from the spirit of the invention or the scopeof the appended claims.

Having thus fully described my invention what I claim as new and desireto secure by Letters Patent of the United States is 1. A music standhaving a rack at the top thereof, lamp shade having a downwardlyextending flange in a vertical plane for mounting upon the upper edge ofthe rack, a lamp pivotally mounted on a horizontal pivot within saidshade, and a supporting shelf beneath the shade and adjacent the loweredge of the rack, the said lamp being normally spring-pressed upwardlywithin and against the under surface of the shade but permittingswinging downward upon said pivot, the said shade having a downwardlyextending border flange to restrict the illuminated field substantiallyto the surface of said rack and the supporting shelf, and the said rackbeing vertically adjustable toward and from the said shelf to vary theintensity of light directed upon the latter without varying the degreeof illumination of the rack.

2. A music stand having a. rack at the top thereof, a lamp shade oftriangular outline having a downwardly extending flange in a verticalplane, for mounting upon the upper edge of said rack, a lamp pivotallymounted within said shade and normally springpressed upwardly within theshade at the vertex of the triangle, and a supporting plate beneath thesaid shade, the said vertex having border flanges to restrict theilluminated field substantially to the surface of said rack, and thesaid plate.

3, A music stand having a rack at the top thereof provided with a convexupper edge, a lamp shade of triangular outline having a downwardlyextending flange curved in a vertical plane, for mountin upon the saidupper edge, the said flange forming the base of the triangle, a lamppivotally mounted beneath said shade and normally springpressed againstthe shade at the vertex of the triangle, and a shelf mounted beneath thesaid shade, and the sides of the triangle adjacent said vertex havingborder flanges diverting from the vertex toward said base, therebyrestricting the illuminating rays from the lamp substantially to thesurface of said rack and shelf.

A. A music stand having a rack at the top thereof, a lamp shaue oftriangular outline detachably mounted at the base of said triangle uponthe upper edge of said rack, and having the vertex extended forward fromsaid rack, and a lamp pivotally mounted within said vertex, whereby theilluminating rays from the lamp will be directed downward upon both therack and other portions of the stand, but will not be directed upwardlyor laterally from said vertex.

5. A music stand having a rack at the top thereof, a lamp shade oftriangular outline detachably mounted at the base of said triangle uponthe upper edge of said rack, and having the vertex extended forward fromsaid rack, the said vertex having border flanges gradually recedingupwardly toward the roof of the shade and forming a light socket in thelatter, and a lamp pivotally mounted within said socket, whereby the i1luminating rays from the lamp will be directed downward upon both therack and other portions of the stand, but will not be directed upwardlyor laterally from said vertex.

6. A music stand having a rack at the top thereof, a lamp shade oftriangular outline detachably mounted at the base of said tri angle uponthe upper edge of said rack, and having the vertex extended forward fromsaid rack, the said vertex having border flanges gradually recedingupwardly toward the roof of the shade and a notched partition connectingsaid border flanges and thereby forming a light pocket at said vertex,and a lamp pivotally mounted within said pocket, whereby the rays fromthe lamp will be directed downward upon the rack and other portions ofthe stand, but will not be directed upwardly or laterally from saidvertex.

7. A music stand having a rack at the-top thereof, a lamp shade oftriangular outline detachably mounted at the base of said triangle uponthe upper edge of said rack, and having the vertex extended forward fromsaid rack and a flat plate adjustably mounted on the under surface ofsaid shade for ad justment toward and from said vertex, and a lamppivotally mounted within said vertex upon said plate for swinging in avertical plane, whereby when the lamp is in its uppermost position, therays therefrom will be directed downward upon the rack and otherportions of the stand.

8. A music stand having a rack at the top thereof, a lamp shade oftriangular outline detachably mounted at the base of said triangle uponthe upper edge of said rack, and having the vertex extended forward fromsaid rack and a flat plate adjustably mount ed on the under surface ofsaid shade for adjustment toward and from said vertex, a lamp pivotallymounted on the under surface of said shade and upon said plate forswinging in a vertical plane, and a shelf mounted adjacent the rack andbeneath the shade, the said rack being vertically adjustable toward andfrom the said shelf to vary the intensity of light directed upon thelatter without varying the degree of illumination of the rack, and thesides of the triangle adjacent said "ertex having border flangesdiverting toward the said base, thereby restricting the rays from thelamp substantially t0 the surface of said rack and shelf.

In witness whereof, I have hereunto set my hand this 4th day of May, A.D. 1929.
